Carbonized Rice Hull (CRH) by Plant Culture
Carbonized rice hull is made from incomplete or partial burning of rice hull.
It is a very good soil fertilizer and conditioner as it contains Phosphorous (P), Potassium (K), Calcium (Ca), Magnesium (Mg), and micro-nutrients vital to growing crops. It makes the clay soil porous because of its loose composition and improves soil structure by increasing bulk density, water holding capacity, and aeration. CRH also harbours good bacteria and it serves as houses for microorganisms.
